“…These include high production costs and lack of integration of aviation biofuels into regulatory frameworks (Carter et al, 2011, Carriquiry et al, 2011Gegg et al 2014), limits in scale-up due to feedstock availability (U.S. DOE, 2011, Seber et al, 2014, environmental and socio-economic consequences of large-scale land-use change and competition with food and feed needs (Searchinger et al 2008;Kretschmer et al, 2009;Serra and Zilbermann, 2013), water consumption associated with biomass cultivation (Scown et al, 2011, Staples et al, 2013, and the time required for scaling-up biomass cultivation and conversion facilities (Richard, 2010). This paper deals with the impact of large-scale deployment of advanced aviation biofuels from perennial grasses such as switchgrass or miscanthus using a set of technologies known as advanced fermentation.…”
